Changes in Selected Properties of Wood Caused by Gamma Radiation

Gamma radiation – as an easy, fast, and effective sterilisation method – changes molecular structures not only in pest’s living cells, but also in wooden cell walls. Radiation-induced depolymerisation causes significant changes in some properties of wood crucial for restoration and for laboratory testing the resistance of wood and wooden products against wood-destroying organisms. Overview of up to date data on the influence of gamma radiation onto some physical, mechanical and chemical properties and on biological resistance against fungal decay are presented.
